Mechanical Strain of Corneal Epithelium Influences the Expression of Genes Implicated in Keratoconus.
Invest Ophthalmol Vis Sci
January 2025
Wilmer Eye Institute, Johns Hopkins Medical Institute, Baltimore, Maryland, United States.
Purpose: Although mechanical injury to the cornea (e.g. chronic eye rubbing) is a known risk factor for keratoconus progression, how it contributes to loss of corneal integrity is not known.

Institute of Bioengineering, Federal Research Center "Fundamentals of Biotechnology" of the Russian Academy of Sciences, Moscow, Russia.
The expression profile of the key genes of biosynthesis (VTC2, GPP, GalDH, and GalLDH) and recycling (MDHAR1, MDHAR4, and MDHAR5) of ascorbate in response to infection with the fungal pathogen Fusarium proliferatum in garlic cultivars resistant (Podnebesny) and sensitive (Dubkovsky) to Fusarium rot was determined. It was found that differences in resistance to Fusarium lead to discrepancies in the dynamics and expression of individual genes of the ascorbate pathway, as well as in the ascorbate content. It was shown that, in response to infection, the expression level of the MDHAR4 gene increases in the resistant cultivar and decreases in the Fusarium-sensitive accession.

Institute of Mathematics, University of Kassel, Heinrich-Plett-Str. 40, Kassel, 34132, Germany.
Accurately identifying the timing and frequency characteristics of impulse components in EEG signals is essential but limited by the Heisenberg uncertainty principle. Inspired by the visual system's ability to identify objects and their locations, we propose a new method that integrates a visual system model with wavelet analysis to calculate both time and frequency features of local impulses in EEG signals. We develop a mathematical model based on invariant pattern recognition by the visual system, combined with wavelet analysis using Krawtchouk functions as the mother wavelet.

Clin Oral Investig
January 2025
Institute of Science and Technology, Division of Periodontics, São Paulo State University (Unesp), Av. Eng. Francisco José Longo, 777, São José dos Campos, São Paulo, 12245-000, Brazil.
Objective: This study aimed to compare the salivary protein profile in individuals with Type 2 Diabetes Mellitus (DM2) and periodontitis and their respective controls.
Methods: Eighty participants were included in the study. The four groups were formed by individuals with DM2 and periodontitis (DM2 + P, n = 20), DM2 without periodontitis (DM2, n = 20), periodontitis without DM2 (P, n = 20) and individuals without periodontitis and without DM2 (H, n = 20).
Acute effects of psilocybin on attention and executive functioning in healthy volunteers: a systematic review and multilevel meta-analysis.
Psychopharmacology (Berl)
January 2025
Department of Clinical and Developmental Neuropsychology, University of Groningen, Groningen, the Netherlands.
Rationale: Psilocybin shows promise for treating neuropsychiatric disorders. However, insight into its acute effects on cognition is lacking. Given the significant role of executive functions in daily life and treatment efficacy, it is crucial to evaluate how psilocybin influences these cognitive domains.
